Toyota 04475-30120-71 Cylinder O/H Kit, Wheel | 5FD50-5FD70

Overview

The 04475-30120-71 CYLINDER O/H KIT, WHEEL is a Toyota wheel cylinder overhaul kit for the service brakes of Toyota diesel forklifts. Over time, the rubber seals and cups inside a wheel cylinder harden, swell, or wear, causing brake fade, fluid seepage, and reduced stopping power. This overhaul kit supplies the seals and components required to rebuild the wheel cylinder, restoring proper hydraulic pressure and dependable braking performance without the cost of a complete cylinder replacement.

Compatibility

The 04475-30120-71 for 3FD80 fits a range of Toyota diesel-powered forklifts. It is specified for:

• Toyota 3FD / 3FDE series, including the 3FD80, 3FDE60, and 3FDE70
• Toyota 5FD 50/60/70 series, including the 5FD50, 5FD60, and 5FD70, as well as the 50-5FD60 and 50-5FD70 variants

Quality and Reliability

Brake components are safety-critical, so seal quality matters. This Toyota wheel cylinder overhaul kit is built to the original part’s dimensions and material specifications, providing seals that stand up to brake fluid, heat, and the demanding duty cycles of material handling work. A correct rebuild with the right kit helps maintain consistent pedal feel and reliable braking in dusty, humid, or high-use environments.

Installation and Maintenance Tips

• Park the forklift on level ground, chock the wheels, and safely support the truck before removing the drive wheel.
• Remove the wheel cylinder and disassemble it carefully, noting the orientation of each seal and cup.
• Inspect the cylinder bore; if you find scoring, pitting, or corrosion, the cylinder may need replacement rather than a reseal.
• Clean all parts and lubricate the new seals with clean brake fluid before assembly.
• Rebuild one side at a time, then bleed the brake system thoroughly and top up the reservoir with the correct fluid.
• Check for leaks and test the brakes before returning the truck to service, and inspect wheel cylinders at every scheduled brake service.
